Severn Trent Services Selected to Provide Tertiary Nitrification to U.K. Utility
FORT WASHINGTON, Pa. - March 21, 2007 - Severn Trent Services have been awarded three separate contracts to provide TETRA(TM) Nitrifying Submerged Aerated Filter (NSAF) technology to Thames Water Utilities, the largest UK water and wastewater treatment company based in Reading, England.
The NSAF systems will be installed at existing facilities at Waddesdon, Culworth and Byfield and will provide "add on" tertiary nitrification to enable the works to consistently meet their ammonia consents.
These are the first TETRA NSAF units to be installed within Thames Water and all are due be installed and in operation by the spring of 2007. The units are of a modular design and have been designed to handle peak flows ranging from 345 to 2,784m3/day.
The TETRA NSAF is an up-flow, fixed film, biological reactor and can be supplied in GRP, steel or concrete variants. The NSAF has proven to be robust and is simple to control, maintain and operate. Its effectiveness in ammonia removal has been demonstrated at numerous installations throughout the United Kingdom over the past 10 years.
